SPECIFICATION forming part of Letters Eatent No. 643,076, dated February6, 1900.

Application filed November 2, 1898. Serial No. 695,335. (No model.)

Figure 1 is a vertical central section of the Valve and surrounding case5 Fig. 2, a top view of valve and case, half in section on the line A Bof Fig. 1; Fig. 3, a topview of valve.

Similar letters refer to similar parts in the several views. I

The case 0, in which the valve moves, is connected at E with the watermain or pipe. Figs. 1 and 2.)

F is a hollow cylinder having a cross-bar G,

to which is attached the valve-stem II, as shown in Fig. 1.

Fitted to the case 0 is the gland I, which forms the stuffing-box J, asshown in Fig. 1.

L shows the gland I cupped to receive a leatherband. (See Fig.1.)Thisbandisriveted to the gland at the upper edge, the lower edge of theband being beveled toward the valve, thus any water passing the packingin box enters back of the leather band, forcing it against the valve,thus preventing any leakage.

(See.

The case C is larger than the valve F, allowing the water to entirelysurround the valve, (see Fig. 1,) thus presenting no resistance to theopening or closing of the valve, the valve 0 requiring only powersufficient to overcome the friction in the stuffing-box, the waterentering and discharging as shown by the ar rows.

The valve-seat M is bored to an angle of about sixty degrees, and thevalve, having an angle of about forty-five degrees, can be worked by acam-lever or other device, with a spring attached to avoid a shock.

What I claim as my invention, and desire to secure by Letters Patent, is

In combination with the cylindrical valve F and a concentricstuffing-box provided with clamping-screws and an internal groove L forpacking, a casing provided with an outlet and valve-seat at its bottom,a lateral inlet,

a raised upper part adapted to receive the said stuffing-box and aninwardly-presented annular rib for guiding the said valve, the latterfitting at the bottom into the said seat and being of less diameter thanthe bore of the said casing in which it works, in order that there maybe a space for fluid around said valve to the level of the saidstuffingbox, substantially as and for the purpose set forth.
